crank sensor replacement.

[doublezero30]

just wondering how hard it is to replace a crank sensor? by the looks of the new sensor its just 1 screw holding it on and then the connector. i just dont know where it is/if there is any specifics to the job. anyone got a DIY or wanna quickly explain the low down for me? thanks.

car is a 03 a4 1.8t quattro automatic if it matters. (not mine)

diy is up on a4mods.com

It's not bad at all.

[doublezero30]

hmm i looked on a4mods and didnt see it. guess im blind. ill check again. thanks

[doublezero30]

are the crank sensor and speed sensor the same thing?

are the crank sensor and speed sensor the same thing?

no

[doublezero30]

welll then i really dont see a write up on a4mods for the crank sensor then. haha

[dougyfresh]

engine speed sensor (engine rotational speed sensor, rpm, etc..): http://a4mods.com/#index.php?page=we...eedsensor.html


What do you mean by "crank sensor"? I thought you mean speed sensor. There are no other sensors on the crankshaft of the 1.8T except the speed sensor.

Are you referring to the sensors in the transmission?

[doublezero30]

^yea thats the diy i saw. sensor looked the same as what the dealer gave me. im really unsure. my buddy got his car vagged and told me he needed a crank sensor so i went to the dealer and got him one at my cost (wholesale). i guess they are the same deal. looks identicle

Do you have the codes he pulled?

I recently replaced my engine speed sensor and if that's the part you're referencing, wasn't too bad to R&R. Took me about 30-40 minutes.

[doublezero30]

nope, and i doubt he knows the code either. but a good shop told him he needed a "world pack crank sensor". i had never heard of it, but went to the dealer and asked for one anyway. got the same thing as in the DIY

[gdawg'05a4]

interesting, never heard of that term either. If it's the same part as in the write up and has the same PN (should be written on the box as well as the sensor), hopefully it solves his problem.

[doublezero30]

^yea ill check that now. didnt even think of it. he's had his EPC light on and CEL and said sometimes its real hard to get it started. so sounds like this will solve the issue based on martini's writeup

edit: yup same part number. ill do it up probably in the parking lot of NSDA's gtg on sunday haha.

[gdawg'05a4]

cool. When mine went, I had the EPC and CEL light as well, not all the time but intermittently in the beginning then got worse. Car would stall when sitting at a light.

[dougyfresh]

Sounds like just different terminology getting thrown around.

Again, that sensor in the a4mods.com write-up is the only engine rotational speed sensor present on the crankshaft of the 1.8 motor. I do not know what else your buddy's problem could be unless the code is referring to the vehicle speed sensor in the transmission (for your speedometer).

[Petabell]

I've been having this problem lately.. EPC and CEL accompanied by random stalling, especially while the car is resting like at a stoplight. It's intermittent, happening usually once a day accompanied by limp mode. The codes i got are:

P0321
Ignition/Dist
Engine speed input
CKT Range/Perf

P0322
Ignition/Dist
Engine speed input
No Signal

sounds like a bad crank sensor??
